Abstract:
(EN) The present invention is a slurry composition for a nonaqueous secondary cell negative electrode, containing: a negative electrode active material that contains a lithium titanium oxide; a binder; and an organic solvent. Furthermore, the binder contains a copolymer that includes a nitrile-group-containing monomer unit as well as at least one of an aliphatic conjugated diene monomer unit and an alkylene structural unit, and the copolymer has a Mooney viscosity (ML1+4, 100°C) of 50-200 inclusive.
(FR) La présente invention concerne une composition de bouillie pour une électrode négative de cellule secondaire non aqueuse, contenant : un matériau actif d'électrode négative qui contient un oxyde de lithium-titane; un liant; et un solvant organique. En outre, le liant contient un copolymère qui comprend une unité monomère contenant un groupe nitrile ainsi qu'une unité monomère diène conjugué aliphatique et/ou une unité structurale alkylène, et le copolymère a une viscosité Mooney (ML1+4, 100°C) de 50 à 200 inclus.
(JA) リチウムチタン酸化物を含む負極活物質と、結着材と、有機溶媒とを含む非水系二次電池負極用スラリー組成物である。さらに、上記結着材が脂肪族共役ジエン単量体単位及びアルキレン構造単位の少なくとも一方と、ニトリル基含有単量体単位とを含有し、且つ、ムーニー粘度(ML1+4、100℃)が50以上200以下である共重合体を含む。
